What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. On a Audi Q4 E-Tron S Line 35 bought as a repairable salvage, the mechanical side is less likely to spring surprises, so your repair estimate should hold up reasonably well.

Before you bid: run the lot through the analyzer, check the car's own record, check the mileage, decode the VIN, and if it carries a marker use the write-off value calculator. Or compare it against another model.
